SPRING BUCKLE.

' Application filed February26, 1923. SeriaI No. 621,17 6.

The object of my invention is to improve upon the buckle of this generalxtype previously invented by meand described Patent No. 1,368,009 granted to me February 8, 1921. More particularly the object of the present invention is so to design and combine the various parts making up .a buckle of this type as to render the entire buckle capable of rapid and cheap manufactureby automatic machinery such as a stamping machine and to render the assembling oftthe same simple, easyand convenient even with unskilled labor. To this general end I have particularly improved the buckle construction by leaving the base open at one end closed at the other end only by a bent-over lip forming the spring-abutment; and by reversely bending out and over, to overlie the body portion, a lip at the opposite or open end of the base to form the strap-grip. A still further important improvement is the employment of a single through-pin passing through aligned perforationsat the ends of the base .fianges and aligned holes in right angular projections on the cam face-plate, whereby this pin serves the double function of pivoting the face-plate and locking the slide within the base.

Another important object of the invention is so to construct the slide with its strap eye that it may be assembled within the base portion in a simple and efficient manner. This is accomplished by offsetting the strap out from the plane of the base and connecting the eye part to the base through a narrow tongue capable of passing clear of the flanges formed on the lips of the base.

The above and further objects of the invention will better be understood by reference to the illustrative embodiment of my invention to which my claims are directed merely for purposes of illustration and not limitation and which is described in the following specification in connection with the accompanying drawings which form part hereof.

In the r win s Fig. l is an exploded View, illustratingall the parts of the buckle in their relative positions immediately before assembling;

F ig2 is an enlarged horizontalsection of the buckle shown in use gripping a strap and Fig. 3 is a section through line III-III of Fig. 2.

The base Ais providedwith two parallel i lips 1 and .2 extending along its longitudinal edges and extending-out at right angles to the base proper. Thes e lips terminate each in inturned flanges3 and 4 respectively, paralleling the base A. One end of the base A is struck over and inward to form the pocket 5, serving as an abutment for the compress on-spring 6. The opposite end of the base A is struck out and over so as to overlie the base A and forms the strap-grip 10, the outer surface of which is preferab y kn rl d .Q o ghen d; h b ts serve as a grip. The ends of the lips 1 and 2 near the grip 10 are provided with aligned perforations 7 and 8 to accoi'mnodate through-pin 9, the further purpose of which is presently to be described.

The slide B is provided preferably with right-angular lips 11 and 12 serving to space the body of the slide B apart from the base A so that within the space thus formed the spring 6 may be nicely accommodated. The far end of the slide B is provided with a bent-over lip forming the spring abutment 13 while the near end of the base A is extended integrally into the tongue portion 14 narrower in extent than the space between the flanges 3 and 4:. The tongue extends into an enlarged portion 15 providing the strapeye 16. This portion 15 r is ofiset from the plane of the slide B so as not to interfere with the lips 3 and 4 during assemblement.

The outer-face plate C is provided with right angular extensions 17 and 18 which at one end, in the locality of the grip 10, are provided with aligned holes 19 and 20 to take the through-pin 9. To assemble the structure. the compression-spring 6 is placed against the slide B with one end against abutment 13. The slide is then slipped into the base 'A, the offset eye 16 clearing the lips 3 and 4, and the spring compressed so that the end 13 will clear the perforations 7 and 8. The holes 19 and 20 are then fitted to align with the perforations 7 and 8. The through-pin 9 is then thrust home through the aligned holes and perforations and is headed over at its far end. The pin 9 then serves as a closure against which the abutment 13 strikes to prevent the dissemblement of the entire buckle. As a further function the pin 9 swivels the cam face-plate C to the base so that the swinging movement from the dash-line position of Fig.2into the full line position of Fig. 2 will cause a strap D to be gripped as indicated.

The preferred material to be employed for the buckle is sheet metal, such as sheet brass which may be nickel or silver plated or the buckle may be made of sheet noble metal.

' What I claim and desire to secure by United States Letters Patent is 1. In a spring buckle in combination, a

base having parallel lips provided with flanges along its longitudinal edges and hav-.

ing one end provided with an interior spring-buttress and the opposite end extending outwardly and back overlying the body of said base to form a strap-grip, transversely aligned perforations being formed in the ends of such lips at the ends adjacent said strap-grip; a slide having a springabutment at its far end and a strap attaching means at its near end and adapted to work within said base under said flanges; a compression-spring lying between said slide and said base and reacting against said abutment; a cam-like face-plate adapted to overlie said base and operate to grip strap against said strap-grip having edge positioned right-angle extensions provided at the end near said grip with aligned holes; and a thorough-pin passing through said holes and perforations to swivel said face plate and form an end-closure for said otherwise open ended base and by means of which the entire structure is assembled.

2. The buckle structure as described in claim -1 and further characterized by the fact that the slide is rovided with a strap eye offset from the p lane of the slide and connected therewith through a tongue narrower than the space between the flanges of the base portion.

3. The buckle structure as described in claim 1 and further characterized by the fact that the three parts-base, slide, and face-plate areall fabricated each solely from one integral piece of sheet metal and that the said three parts are completely assembled by a single through-pin.

In "witness whereof I have signed my name to this specification this 2nd day of February, 1923.
